Yes it is, but not to feed into a DOM, which does its own escaping when it
meets the ampersand.

Yes, because the text-method would un-escape again.

And here you get the 'raw' xml data of the node, exactly as you entered it.

(Besides that: the original VB snippet you sent also has a quite dangerous
form of double escaping going on. If you really need to implement your own
routines for this, it would be advisable to escape the ampersands first,
then the others...)
